Facebook Page Likes are reported to Next Big Sound two different ways: public Facebook data from their API and through user authenticated Facebook Insights connections. The former includes competitive artists and the latter includes a geographic breakdown.

Page Likes from public data and Insights have similar day-to-day values, but do not always match exactly. For the most part, values trend closely together, but for a handful of time periods there have been large discrepancies. Note that the Facebook Insights data matches exactly what is shown in the Facebook Insights dashboard. This reporting discrepancy is a known bug on Facebook’s end, we will update when more.
